PlayStation Development Network

What do I do?
Your task is simple. Make a game for the PlayStation 1.
You have 6 months to do it in, so there is plenty of time.

You may use the Net Yaroze SDK, PSY-Q SDK, or any other libraries you wish.
There are no limitations to what your mind can create!

The scoring system is based on a point calculator, as well as manual votes.
The more points and votes you score, the higher your game will be rated which will place you first.

I need help programming for the PlayStation 1, or I am just simply stuck
If you get stuck or need some help, join our IRC channel on EFnet (irc.eversible.net) #psxdev
You will be able to chat with other members, as well as make new friends who also love the PlayStation 1.
(See here for help on joining or if you don't know what IRC is)

This sounds like fun

Also we are on Hack A Day
http://hackaday.com/2012/12/05/hackaday ... er-5-2012/

Is it that this announcement is so new or the PSX scene is small?

Also, what's the best resource for PSX Chipmunk BASIC? That seems to be my best chance for entering this contest.

Er, one more question: The prize that entails an actual PSX CD with label. Will this be mastered to run on non-modded consoles?

PSX scene seems quite small these days. I might create my own website and do my part for the PSX scene.

The PSX scene is very small. Thats why I made this website. I was sick and tired of all the other websites that were poorly maintained, had dead links everywhere, and had information missing.

The main goal here was to try and get old members from the old scene, as well as new members back making things for the PlayStation 1 and be the home of PlayStation 1 development resources and information that will be up 24/7.

Don't use Chipmunk BASIC. Use PSY-Q
It's the full Sony SDK that the professionals used. It was leaked many years ago.
Another option is to use the Net Yaroze SDK. However, this is just a cut-down version of PSY-Q with annoying limitations in use. Sony does not care about PSY-Q. The PlayStation 1 is 'obsolete' to them and they simply just ignore the console all together. It is making them no money. It's a good thing for us, as we now may learn from it.

Feel free to make another website. In all honesty though, It wont help a single bit.
I added the homebrew section here with a member area for FTP uploading so we host your game for you.
We are already high on the Google search index list too.

You mistake my intent, I wouldn't be trying to compete with this site. I'd more than likely be talking about the games, and what I liked about them - a place that promotes people to talk about their PSX gaming experiences. There are very few dedicated PSX sites about these days.

Ah, my mistake. It seems as if a little communication mix up took place
Anyway, I don't know if it would pick up as the PSX gaming days are over

You never know. There must be other people out there like us, but they just haven't found websites like this.

Thanks to Hackaday I have now I'm sure others will follow.

Downloaded PSY-Q already and getting to grips with it. This looks like fun!

Awesome. Just, awesome

Oh, and the CD-ROM prize is just your game burned to a normal CD-R.
You will still need a modchip to play it.

I will update the prize list soon so that EVERY entry gets a compilation disc (all entries burned and selectable via a menu). Therefor, everyone is a winner
If this becomes really popular, I will make the prizes development kit items for the next competition, such as a DTL-H2500 card, or PSX Debugger.

Hey guys,

Thanks to HackADay too, I'm gonna enter the comp. It's been a while, the last console I wrote any code for was the N64.. so gonna whip up a game. Looks good *looks at his trusty PS1 with modchip*..

I'll let you know how my progress is, and yes, just downloaded Psy-Q..

Awesome

Can i be in that? ^^ Would be soooo cool

Hm, I might enter, but I have two short questions:

1) Regarding the rule "You can not use an existing game you have been working on.": Can I reuse code I've already written, like helper functions for graphics, text display and such?

2) Is the game required to have sound, or does no sound simply mean no points for any of the sound-related goals? Because I cannot compose at all and I'm not sure about using PD music or something.

1) You can re-use code already written. You just can't enter a game you have been working on before the competition was started (not that we would know anyway).

2) Music/sound is not required but you will not get any points. See here if you want to play a simple loop of music.

i could only offer my in development progress PC game. No time to port it for ps1
maybe i'm within the next Compo.

(rewrite)arkanoid for ps1 under construction
